“What is it like to be the arm candy in a relationship, because she’s the very serious person?” Colbert asked Clooney. “She must say like, ‘We’re going to meet extremely intelligent people tonight – these are not show folk. Just be shiny and pretty.”

“That’s mostly what I do,” Clooney confirmed.

Colbert congratulated the 54-year-old actor and director on his nuptials to Amal last year as the couple approaches their first wedding anniversary on Sept. 27.

The 51-year-old Late Show host even gave the Oscar winner a belated wedding present after feigning disappointment that he wasn’t invited to their wedding in Italy. (He joked that the two had just met before the taping.)

A paperweight from Tiffany’s with the engraving, “I don’t know you.” At least Colbert’s truthful!

Clooney, who appeared on the show without a project to promote, went on to discuss a fake movie he “filmed” called Decision Strike, where he “plays” Secretary General Clooney tasked to stop the world from falling victim to a nuclear bomb.

They threw to three pre-taped bits, including one “scene” where Clooney – dressed in a tux – said he was too busy romancing a girl in the room to save the universe.

“I did my own sex,” Clooney later ad-libbed when Colbert asked about the possible CGI nature of the scene. “In fact, I do my own sex – the audience deserves it.”

Earlier this summer, George and Amal Clooney enjoyed a romantic evening together in Lake Como, Italy. Press play to find out more.
